7 Application filed October 16,1902. Serial No. l27, l6. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH FIsoHLER, a citizen of the UnitedStates,residing at Silverton, county of San Juan, State of Colorado, haveinvented an Improvement in Fuse-Splitters and Oa'p-Crimpers; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to a device which is especially designed forsplittingfuse and cri mping caps upon the ends thereof in readiness.

. which the blade for use;

It consists of a pair of handles pivoted together, the operating end ofone: consisting of afu's'e-splitting blade an'daone-half of the crimpingsegment, and the operating end of the other handle carrying theelasticallymo'unted splitting-blocks in conjunction with operates andalso carrying the other half of the crimper. The side walls of thesplitting-blocks may also be formed to receive the fuse transversely,so'thatthe same bladew'ill serve to cut it into desired lengths.

Referring to the accompanying drawings, Figure 1 is a side view showingthe device open. Fig. 2 is a section on mm of Fig. 4. Fig. 3 is across-section on the line y 3/ of Fig. 4, showing the splittingblockswith their spring sides or extensions and attachment to thejaw. Fig. 4is a side view with jawsclosed.

It is the object of this invention to provide a convenient tool by whichall the work of preparingfuse and afiixing the explosion-caps thereonmay be easily efiected.

As shown in the drawings, A and B are handles crossing each other andpivoted together, as shown at O. The extension of one of these handles Abeyond the pivot-point is formed intoa sufficiently-thin sharp blade 2.The extension of the other handle B carries the jaw, in conjunction withwhich the blade 2 may operate, first, to cut oil? the fuse and make aclean square cut to fit the cap and after loading the hole to split thefuse a short distance from the end, and thus prepare it for ignition.The splitting-block consists of two elastic blades 3, the lower ends ofwhich are riveted or otherwise secured to the lower end of theextensionB of the handle B. These sides 3 3 extend upward and haveformed near the upper ends the inwardly-projecting blocks or surfaces 4,which nearly or quite meet each other centrally between the sides 3,leaving a space into which the blade 2 may descend,

the sides 3 3 being sufficiently elastic .to allow the blocks toseparate as the bladepasses between them and to again close togetherwhen the blade'is removed by opening the jaws. Above the blocks 4 thesides 3 extend, as at 3, forming guides between which the fuse is heldcentrally when the end is inserted for the purpose of being split. Thesesides 3 also have formed in them the semicircular grooves 5, which aretransversely in line with each other and the bottoms of which are flushwith the surfaces of the blocks 4:. This allows the fuse to be laid intothe grooves 5 transversely of the blade 2 and supportingblocks 4, andwhen the handles are closed together the blade will cut the fusesquarely across, because it lies solid on both the blocks 4, and beingequally supported the blade passes squarely across and into the spacebetween the blocks, which are slightly separated by the movement.

, This square end of the fuse is then ready to beinserted and securedwithin the cap as follows: Behind the blade 2 and the opposing jaw 4 thesemicircular transversegrooves 7 are made in the two jaws opposing eachother, so that when closed together they will form an essentiallycircular hole transversely through the twojaws. Within these jaws thecap is placed, the fuse fitted into the end of the cap, and by closingthe handlesthe cap will be criinped firmly upon the end of the fuse andthe connection will be waterproof. After the hole has been loaded theprojecting end of the fuse is split, so that it may be quickly ignited,which is necessary when a number of holes are to be fired at once. To dothis, it is laid lengthwise between the upwardly-projecting sides 3",and is thus held centrally in place. forced down by closing the handlespasses through the fuse and into the space between theblocks 4 as thehandles are closed, thus splitting the fuse cleanly and evenly. As soon.as the blade is withdrawn by opening the handles the blocks closetogether again.

In order to limitthe rearward movement of' the fuse, and thus preventits going beyond the splitting-block, I have shown a block or stop 6,which projects upwardly at the rear end of the blocks 4 and inline withthe open The blade 2 being thenporting,
